An Omnidirectional antenna generates a beam in all directions and is defined as one "having an essentially non-directional pattern in a given plane and a directional pattern in any orthogonal plane".
A Smart antenna however, often referred to as an adaptive antenna, utilises adaptive DSP based techniques and digital technology. The original analogue signals must be converted to digital form through the use of digital converters.
Consequently, the nulling of a given interference and the steering of the main beam to a known direction can be achieved by changing the phases and amplitudes of the signals in individual elements of the array.

How does a smart antenna work?
A smart antenna is used to identify signal signature and to track an antenna beam on the target. Some are for beamforming which is used to create the radiation pattern of the antenna.

What type of antenna is used in mobile phones?
Answer: The modern mobile phone uses a fractal antenna. History: Previous generations of mobile phones used the dipole antenna. (Some protruded, others were retractable.) Details: A mobile phone must work in any orientation, so the antenna must be omnidirectional. Today's various cellular networks have multiple frequency bands. Smart phones have a variety of protocols (GPRS, PCS, Bluetooth, near-field, Ant, WiFi) requiring several transmitters and receivers working at a wide range of frequencies. Fitting two of more antenna in the same case increases complexity and costs. The only single antenna that can handle all these demands is fractal, thus, the entire industry now uses one or another style of fractal antenna.
